Abstract
MATIJASEVICH, Alicia et al. Method for estimating infant mortality and low birth weight indicators for Brazilian municipalities, 2012. Epidemiol. Serv. Saúde [online]. 2016, vol.25, n.3, pp.637-646. ISSN 1679-4974. http://dx.doi.org/10.5123/S1679-49742016000300020.
OBJECTIVE:
to present a method for estimating low birth weight (LBW) prevalence and infant mortality rate (IMR) indicators for Brazilian municipalities, so as to incorporate considerations with regard to sampling fluctuation.
METHODS:
binomial and Poisson distributions were used to estimate 95% confidence intervals (95%CI); when the number of infant deaths was zero, the upper limit of the 95%CI was estimated by the cross-multiplication method; indicators were estimated for the year 2012 for demonstration purposes.
RESULTS:
a slight increase in LBW and a decrease in IMR were detected as municipality population size increased; LBW estimates were more accurate than those for IMR; single-year estimates showed large width 95%CI in small municipalities and low reliability.
CONCLUSION:
an electronic spreadsheet was developed which will allow service managers to estimate the precision of these indicators for their municipalities.
